Install Code Search on a separate RHEL/CentOS 7.3 server

Follow these instructions to install TeamForge Code Search on a separate RHEL/CentOS 7.3 server.

Attention: Installing or upgrading TeamForge needs root privileges. You must log on as root or use a root shell to install or upgrade TeamForge.

Install Red Hat Enterprise Linux/CentOS 7.3 and log in as root.
- Don't customize your installation. Select only the default packages list.
- Red Hat Enterprise Linux/CentOS 6.8 is also supported. See TeamForge installation requirements.
- The host must be registered with the Red Hat Network if you are using Red Hat Enterprise Linux.
- See the Red Hat installation guide for help.
Check your basic networking setup. See Set up networking for your TeamForge server for details.
Configure your TeamForge installation repository.
- TeamForge installation repository configuration for sites with internet access
1. Contact the CollabNet Support and download the TeamForge 17.1 installation repository package to /tmp.
2. Install the repository package.
  - yum install -y /tmp/collabnet-teamforge-repo-17.1-1.noarch.rpm
3. Refresh your repository cache.
  - yum clean all
- TeamForge installation repository configuration for sites without internet access
1. Contact the CollabNet Support to get the auxiliary installer package for TeamForge 17.1 disconnected installation and save it in /tmp.
  - Red Hat Enterprise Linux/CentOS 7.3 64 bit RPM package: CTF-Disconnected-media-17.1.556-48.rhel7.x86_64.rpm
    Note: In addition to the above CentOS 7.3 64 bit RPM package, you must get the following CentOS 7.3 compatibility RPM, which is required for TeamForge 17.1 disconnected media installation on CentOS 7.3 profile: compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm.
2. Unpack the disconnected installation package.
  - rpm -ivh <package-name>
3. Unpack the compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm package if you are installing TeamForge 17.1 on CentOS 7.3.
  - rpm -ivh compat-ctf-dc-media-1.0-1.el7.centos.noarch.rpm
4. Note: If the Red Hat Enterprise Linux/CentOS installation DVD is mounted already, skip the following instructions. If not, mount the DVD.
  Mount the Red Hat Enterprise Linux/CentOS installation DVD. The DVD contains the necessary software and utilities required for installing TeamForge without internet access.
  In the following commands, replace "cdrom" with the identifier for your server's CD/DVD drive, if necessary.
  - cd /media/
  - mkdir cdrom
  - mount /dev/cdrom ./cdrom/
  If there are any spaces in the automount, unmount it first and mount it as a filepath, with no spaces.
5. Create a yum configuration file that points to the Red Hat Enterprise Linux/CentOS installation DVD.
  - vi /etc/yum.repos.d/cdrom.repo
  Here's a sample yum configuration file.
```
[RHEL-CDROM] 
name=RHEL CDRom 			
baseurl=file:///media/cdrom/Server/
gpgfile=file:///media/cdrom/RPM-GPG-KEY-redhat-release 
enabled=1
gpgcheck=0
```
6. Verify your yum configuration files.
  - yum list httpd
  - yum list apr
Install Code Search.
- yum install teamforge-codesearch
Copy the site-options.conf file from the Application Server to the /opt/collabnet/teamforge/etc/site-options.conf directory of the Code Search Server.
Configure the the site-options.conf file.
1. Configure the services and domain name tokens.
  Important: If you choose not to use the Application Server's site-options.conf file, then don't forget to copy the value of AUTO_DATA token from the Application Server.
```
my.codesearch.host:SERVICES = codesearch
```
```
my.app.host:SERVICES = ctfcore ctfcore-database mail search etl ctfcore-datamart subversion 
cvs gerrit gerrit-database binary binary-database service-monitor reviewboard reviewboard-database
```
  Note: The above example lists all possible services that could run on the TeamForge Application Server. You may have to adjust the list of services for my.app.host:SERVICES token to suit your site's distributed server setup, if required.
Save the site-options.conf file.
Deploy services.
- /opt/collabnet/teamforge/bin/teamforge provision
The "provision" command prompts for response before it bootstraps or migrates data during TeamForge installation and upgrade respectively. Enter "Yes" or "No" to proceed. For more information, see The teamforge script.
